摘要
高速铁路钢轨暂行技术条件要求成品钢轨的w[O]≤20×10^(-6),文中进行了钢中氧控制的热力学分析,对SiCa和SiBaCa合金的无铝脱氧进行了工业试验,分析了钢中夹杂物的行为。试验结果:采用SiBaCa合金脱氧能够控制钢中w[O]≤20×10^(-6),且钢中夹杂物呈现复合状态。
The provisional technic qualification of high speed railway steel needs [0]≤20×10^-6 in final production.The paper analyses the thermodynamic process of controlling oxygen in steel, the industry trial for SiCa and SiBaCa alloy no - aluminum deoxygen,and the action of inclusion in steel.The [0] in steel can be controlled less than 20×10^-6 by SiBaCa alloy deoxygen, and the inclusion is complex.
